    Psychological values as protective factors against sexist attitudes

    in preadolescents

    Marta Ferragut, Mara Jos Blanca and Margarita Ortiz-TalloUniversidad de Mlaga

    Sexism is considered one of the chief variables that maintains

    sex inequalities (Moya, 2004), and it can even be a precursor

    of domestic violence. Glick and Fiske (2001) underline two

    differentiated forms of sexism that coexist in contemporary

    society: hostile sexism and benevolent sexism. Hostile sexism

    reflects beliefs about women that consider them an inferior group,

    with negative stereotypes that foment discrimination. Benevolentsexism refers to beliefs about women considered a group that

    must be protected because they are weak. Numerous studies

    provide results about gender differences in hostile sexism, where

    men score higher than women. However, when studying gender

    differences in benevolent sexism, there are discrepancies. Some

    authors, like Glick and Fiske (1996), found significant differences

    between men and women in five out of the six studies presented,

    with higher scores in the men in this variable. Other authors

    found significant differences, with women scoring higher (Lemus,

    Castillo, Moya, Padilla, & Ryan, 2008). There are also studies that

    have either found differences or no differences, depending on age

    (Garaigordobil & Aliri, 2011). And lastly, some works have foundno significant differences in this variable (Ferragut, Ortiz-Tallo,

    & Blanca, 2011). Thus, benevolent sexism emerges as a complex

    variable that deserves more scientific contributions.

    Diverse investigations have clearly established the relation

    between beliefs and attitudes towards violence (cognitive

    and affective components) and discriminatory behaviors and

    perpetration of violence (behavioral component) (Carrin, 2010;

    Daz-Aguado, 2002, 2004). Women usually present significantly

    lower values in sexist attitudes and attitudes of justification

    of violence, whereas men have significantly higher values in

    authoritarianism (Daz-Aguado, Martnez Arias, & Martn Seoane,

    2004).

    Abstract Resumen

    Background: Sexist attitudes are one of the factors that justify domestic

    violence. Positive psychology can provide keys to prevent sexist violence at

    an early age. Psychological values are a group of psychological strengths in

    a persons development. They provide important clues for the prevention of

    gender-based violence. Method: This study presents an assessment of two

    groups of variables, sexist attitudes and beliefs and psychological values,

    in a sample of 449 (213 boys and 236 girls) preadolescents from various

    schools (mean age: 12). We analyze the relationship between these variables.

    We used the Values in Action Inventory (VIA-Y), the Questionnaire of

    Attitudes towards Diversity and Violence (CADV) and the Ambivalent

    Sexism Inventory (ASI). Results: The results show that sexism variables

    are related to each other and negatively to the psychological values in boys

    and girls. Conclusions: We discuss the importance of prevention programs

    being appropriately developed and, probably, different programs for each

    sex.

    Keywords: sexism, psychological values, prevention of domestic violence,

    positive psychology, adolescents.

    Psychological values as protective factors against sexist attitudes in preadolescents

    39

    In the study carried out by Viniegra (2007) with the questionnaire

    Actitudes hacia la Diversidad y la Violencia (CADV; in English,

    Attitudes towards Diversity and Violence), girls expressed less

    agreement than boys with intolerant beliefs and justification of

    violence. Similarly, Daz-Aguado (2004), in an investigation for

    the Instituto de la Mujer (Womens Institute), found that boys

    justify violence more than girls. In contrast, girls obtain higherscores in the rejection of violence and sexist beliefs (Daz-Aguado,

    2003).

    Alternatively, Positive Psychology is based on the values and

    psychological strengths that are also essential in the study of the

    problems of the human being. Peterson and Seligman (2004)

    focused on the study of these values and strengths that favor

    peoples growth. These authors propose a classification into six

    essential values that are divided into 24 strengths, understood as a

    series of positive traits reflected in thoughts, feelings, and behavior.

    These six values are: wisdom and knowledge, courage, humanity,

    justice, temperance, and transcendence. Psychological values are

    essential for peoples development and of particular importance

    during developmental stages such as preadolescence. In this sense,

    they may protect youngsters from negative aspects such as sexism

    and violence during this stage.

    However, despite the growing interest in the research of positive

    psychology, there is very little bibliography in the scientific

    literature about this essential stage of development, as well as

    about its relation with sexist attitudes and violence.

    Some investigations have related sexism and attitudes towards

    violence to specific psychological strengths, for example, the work

    of Wellman, Czopp and Geers (2009), in which, along with the aim

    of egalitarian goals, the strength of hope is noted as a key factor

    to deal with prejudice. With regard to the strengths included in the

    value temperance, Vohs, Finkenauer, and Baumeister (2011) found

    a positive relation with the quality of the dating relation, whereas

    Finkel et al., (2009) suggest that a defi

    cit in self-regulation may berelated to the perpetration of gender violence by young people.

    In recent years, numerous investigations have been carried out

    in Spain and important efforts have been made to study the diverse

    factors related to couple violence, sexism, and violent attitudes in

    adults (Andrs-Pueyo & Echebura, 2010; Echebura, Sarasua,

    Zubizarreta, & de Corral, 2009; Fernndez-Montalvo & Echebura,

    2008; Ferrer, Bosch, Ramis, Torres, & Navarro, 2006; Lonaz, Ortiz-

    Tallo, Snchez, & Ferragut, 2011; Ortiz-Tallo, Cardenal, Blanca,

    Snchez, & Morales, 2007; Ortiz-Tallo, Fierro, Blanca, Cardenal,

    & Snchez, 2006). Most of the research in the field of psychology

    positive and psychological values was conducted with adult

    population and, to a lesser degree, with adolescents (Zubieta, 2008).

    However, few investigations have studied the relation between

    the positive aspects of the human beingsuch as psychologicalvaluesthat could serve as protection and prevention factors

    against sexist attitudes and beliefs. The relation between these

    variables could have an impact on future programs of prevention of

    domestic violence. Preadolescence is a crucial age in the formation

    of attitudes and beliefs that are consolidated throughout life.

    Previous studies have found gender differences in these variables

    at this stage of development (Ferragut, Ortiz-Tallo, & Blanca,

    2011; Garaigordobil & Aliri, 2011; Karris, 2009; Shimai, Otake,

    Park, Peterson, & Seligman, 2004; Viniegra, 2007), which leads us

    to differentiate boys and girls in the present study.

    Thus, the main goal of study is to analyze the relation between

    two sets of variables: on the one hand, sexist attitudes and beliefs

    and, on the other, psychological values, differentiating between

    preadolescent boys and girls.

    Method

    Participants

    In this study, there were 449 participants (213 boys and 236

    girls) from the first grade of Compulsory Secondary Education,

    aged between 11 and 13 years (M= 12.14, SD= 0.51), belonging

    to 27 classrooms of 8 public schools of Malaga (capital city) and

    province.

    With regard to the participants family situation, 84.7% of the

    sample has siblings, and of them, 47.4% has a single sibling. Of

    the sample of children, 72.8% live with their family of origin, that

    is, parents and siblings, 10.8% live with their mother and siblings,

    and 5.6% live in reconstructed families, that is, with the parents

    new partner. With regard to the country of origin, 83.4% of the

    sample is of Spanish nationality, and the rest belong to 21 different

    nationalities.

    Instruments

    To assess sexism, we administered the Inventario de Sexismo

    Ambivalente para adolescentes (ISA, in English, the Ambivalent

    Sexism Inventory for adolescences; Lemus et al., 2008). It has

    20 items that are rated on a 6-point Likert-type response format,

    ranging from 1 (Strongly disagree) to 6 (Strongly agree). The

    questionnaire yields a total score of sexism and two scores in the

    following factors: hostile sexism (reflecting negative attitudes

    towards women) and benevolent sexism (reflecting protective

    attitudes towards women, who are stereotyped and undervalued).

    In the general scale, a Cronbach reliability coefficient of= .83

    was obtained, for hostile sexism,

    = .84, and for benevolentsexism, = .77.

    To assess attitudes towards violence, we administered the

    "Cuestionario de Actitudes hacia la Diversidad y la Violencia"

    (CADV, In English, the Questionnaire of Attitudes towards

    Diversity and Violence; Daz-Aguado & Martnez Arias, 2004).

    This questionnaire has 56 items and is rated on a 7-point Likert-

    type response format, ranging from 1 (Strongly disagree) to 7

    (Strongly agree). It provides scores in four factors. The present

    study focuses on the factor called Sexist beliefs and justification of

    domestic violence, in view of our proposed goals. This factor had

    good internal consistency, with = .85.

    Lastly, to assess psychological strengths, we used the Values

    in Action for Youth (VIA-Y; Park & Peterson, 2006). It has 198

    items and is rated on a 5-point Likert-type response format,ranging from 1 (Very different from me) to 5 (Very like me). We

    used the Spanish adaptation of Vzquez and Hervs (2007). This

    questionnaire assesses 24 psychological strengths that are grouped

    into the following six values with scores that range between 1 and

    5 points: (a) Wisdom and knowledge (which include the strengths

    of creativity, curiosity, love of learning, open-mindedness, and

    perspective); (b) Courage (which includes bravery, persistence,

    authenticity, and zest); (c) Humanity (which implies love, kindness,

    and social intelligence); (d) Justice (in which are found teamwork,

    fairness, and leadership); (e) Temperance (which includes

    forgiveness, modesty, prudence, and self-regulation); and (f)

    Transcendence (which includes appreciation of beauty, gratitude,

    hope, humor, and relogiousness). The internal consistency of

    questionnaire ranges between the values of= .72 and = .91 for

    the diverse scales of the questionnaire.

    Procedure

    The investigators informed the school directors and the school

    parents association about the goals of the study and the procedure

    to be followed. The schools that accepted to participate in the

    investigation were in charge of requesting the parents informed

    consent.

    The data were collected during the first trimester of the course

    2010-2011 in two 1-hour sessions. This data collection was

    proposed as an anonymous and voluntary group activity in the

    schools.The students collectively filled out the numbered tests in their

    classrooms, during their normal class schedules.

    Data analysis

    We performed Students t-test for the comparison of means of

    independent samples in order to analyze gender differences in the

    scores, and the corresponding measures of effect size by means of

    Cohens dfor each variable.

    Subsequently, we conducted a canonical correlational

    analysis for each gender. The first set of variables was made up

    of Hostile sexism, Benevolent sexism, and Sexist beliefs and

    justification of domestic violence. The second set was made up

    of the 6 Psychological values: Wisdom and knowledge, Courage,Humanity, Justice, Temperance, and Transcendence.

    Results

    The comparison of means for gender differences was significant

    for each one of the variables studied, showing that the girls obtained

    higher scores in all six psychological values and lower scores in the

    variables that make up sexism. The effect size observed was small

    in most of the variables. This information is presented in Table 1.

    Using Wilks criterion, the canonical correlational analysis for

    the girls yielded the first statistically significant canonical variable,

    F(18, 642)= 4.01, p

    Psychological values as protective factors against sexist attitudes in preadolescents

    Discussion

    The goal of this study was to analyze the relation between two

    groups of variables, sexism on the one hand, and psychological

    values on the other, in groups of preadolescent boys and girls.

    In the results,firstly, significant gender differences were obtained

    in all the variables studied, as expected. The girls express a lower

    degree of agreement with sexist attitudes and hostile sexism. Other

    studies of adolescents have systematically found this same result

    (Glick & Fiske, 1996; Lemus et al., 2008). Likewise, in the present

    work, the preadolescent girls also scored lower than the boys

    in benevolent sexism. In this sample, the boys expressed more

    agreement with stereotyped beliefs about women that consider

    them as belonging to a group that should be protected; the opposite

    was observed in preadolescent girls.

    Regarding the psychological values, at this age, the girls

    present signifi

    cantly higher means than the boys in all six valuesanalyzed. This result is congruent with data from diverse previous

    investigations that analyze the strengths, and it is a common

    constant in several countries (Ferragut, Ortiz-Tallo, & Blanca,

    2011; Gimnez, 2009; Park & Peterson, 2003; Shimai et al.,

    2006).

    Thus, sexist attitudes differentiated between boys and girls at

    very early ages, so that, already in secondary school, boys display

    more negative attitudes towards women than girls. These boys also

    present fewer positive traits in comparison to the girls, obtaining

    lower scores in the psychological values.

    The results of this study also show that sexist variables are

    related to each other, and inversely to the psychological values.

    This occurs both in the group of boys and of girls. Within this

    context, we can state that the psychological values are involved in

    the formation of sexist beliefs and attitudes. There are no studies of

    this aspect that provide evidence of this relation. Other authors have

    investigated the aspects that differentiate boys and girls, findingthat the relational aspect of sexism differentiates the genders and is

    involved in sexist beliefs (Garca et al., 2010).

    In the canonical correlational analysis, we observed in the girls

    that the variable with the greatest weight in the set of sexist variables

    was hostile sexism. In the psychological values, the variable with

    the greatest loading was humanity. That is, in the group of girls, the

    development of psychological values, especially those that include

    approaching others, empathy, and knowledge of social situations,

    is inversely related to the development of attitudes of rejection of

    women, considering them inferior, and in a stereotyped way.

    But in the group of boys, the variable from the first set with

    the greatest loading is sexist beliefs and justification of domestic

    violence, and from the second set, the value of transcendence.

    Thus, sexist beliefs that justify violence towards women are related

    to a lower capacity of gratitude, hope, humor, or religiousness (the

    transcendence value).

    Studies of the psychological strengths and values have related

    them with variables such as well-being, satisfaction, or even with

    psychopathology, such as depression or stress (Gimnez, 2010;

    Park & Peterson, 2009), in which these variables always emerge as

    predictors of psychological health.

    In this sense, preadolescents who have high scores in the

    psychological values show less sexist attitudes towards women.

    Considering these data, we can state that, in the study of sexist

    attitudes, education in psychological values should be taken

    into account as a preventive measure. Moreover, it would also

    be interesting to focus on support or intervention, especially inmales.

    This study is part of a longitudinal research project to study

    the variables presented herein throughout secondary education.

    Thus, we will attempt to progressively solve some of the current

    limitations. We think it would be interesting to study the evolution

    of these data during adolescence. Future research could have the

    goals of expanding the number of participants, and including

    different ages. Lastly, it would be relevant to carry out interventions

    in the psychological values and to observe whether changes are

    produced in the variables related to sexism.
